NTE7188
Integrated Circuit
TV & CRT Vertical Output with
Bus Control Support
Description:
The NTE7188 is a vertical deflection output IC in a 7−Lead Staggered TO220 type package designed
for high image quality TV and CRT displays that supports the use of a bus control system signal−processing IC. The sawtooth waveform from the control system signal−processing IC can directly drive
the deflection yoke (including the DC components). Since the NTE7188 provides a maximum deflection current of 1.8 AP−P, it is optimal for small and medium size CRTs.
